Lay flat sprinkler hoses are widely use in S. Korea due to its reasonable price and flexibility. However, it applies a lot of water for a short time in a field that potentially causing unbalanced irrigation. In addition, there have been not many studies on characteristics such as irrigation uniformity. In this regards, the purpose of this study was to provide fundamental data for the design and operation of lay flat sprinkler by evaluating the irrigation uniformity and the watering pattern according to the change of water pressure. The most important characteristics for the uniformity were a pattern, number, and diameter of the holes on the lay flat sprinkler hoses. The amount of irrigation was different up to 2.3 times under the same (or about same) water pressure. Statistical uniformity (CV) of the sprinkler hose A, B, C showed good to fair, good, and fair respectively. Emission uniformity (EU) of the sprinkler hose A, B, and C classified good, excellent to good, and fair individually. The results of this study would be useful for proper water management by providing fundamental data such as water pressure level, spacing, and water management when installing lay flat sprinkler hoses in crop cultivating sites.
